IMPROVEMENT IN MACHINES FOR FORMING THE WARP-EYES 0F WIRE HEDDLES.

Specification forming part of Letters Patent To all whom it may concernBe it known that I, ABIJAH J. WILLIAMS, of Utica, in the county ofOneida and State of New York, have invented a new and useful Improvementin Machines for Forming the Warp-Eyes of Wire Heddles; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being bad to the accom panying drawings, formingpart of this specification, in which- Figure 1 is a plan view of myimproved machine adjusted to the weaving-eye of a heddle before beingoperated. Fig. 2 is a similar view, with the wire heddle as it appearsafter being completed. Fig. 3 is a vertical longitudinal section ofthesamein the lineww of Fig. 2. Fig. 4 is a front view of a wire heddlecomplete and ready for use, and Fig. 5 a top view of my machine inconnection with the wiretwisting mechanism.

The object of my invention is to form the weaving-eyes of wire heddlesin a simpler and more perfect manner than heretofore, and without theuse of theexpensive and complicated mechanism heretofore used forproducing them by external pressure.

The nature of my invention consists in both forming and stretching theweaving or warp eyes of wire heddles by an implement introduced into thewarp-eye, or between the wires, and actuated by a slide while in thesaid eyes, whereby the warp-eyes are shaped and stretched, and, at thesame time, the twists on each side of the eye are forced tightlytogether, and caused to remain so without an additional operation offlattening or compressing the twists from the outside of the eyes, aswill be hereinafter described.

In the accompanying drawings, A represents a supporting and guidingplate, to which two lever-jaws, B B, and a reciprocating slide, 0, areattached, as represented. Each jaw B has one-half of the eye-former a aconstructed upon one of its ends, as shown, and at the base of the partsforming the eye-former a a thereis a shoulder, b, for the wires of thebeddle to bear against while the eye-former is shaping and stretchingthe eyes thereof. The rear portions or handles of the lever-jaws areinclined on both edges from the point 0 to No. 1.95,!i9 l, datedSeptember 11, 1877; application filed March 3, 1877.

their extremities, and these inclined portions cause the handles todiverge from one another. The reciprocating slide 0 is fitted in aguide, 0 of the supporting-plate A, and under the handles of thelever-jaws, so as to abut against the shoulder d formed on thesupporting-plate A, when it has made its full stroke, for the purpose ofclosing the jaws B B. The leverjaws are caused to open and close as theslide moves back and forth by means of two pairs ofstnds or pins,e e,projecting out from the face of the slide, said pins forcing the outerends of the lever-jaws apart when the slide moves in one direction, andvice versa when it moves in an opposite direction. The forming ends ofthe jaws close together when the slide moves in the direction of thearrow 1, and separate when the slide moves in the direction of the arrow2. The movement of the slide for closing the jaws B B is effected bymeans of a spring, E, which is attached by one end to thesupporting'plate and by its other end to the slide, as shown, and themovement for opening the jaws is effected by any appropriate mechanismconnected with or arranged in proper relation to it. The leverjaws arefitted to the plate A under a cap, 0 and pivoted, as at f f, in such amanner that they are kept steady and firm, and still have a perfectfreedom to vibrate on their pivots.

The longitudinal movement of the slide 0 is controlled by a stop-pin, g,which works loosely in an oblong slot, h, formed in the supporting-plateA, and this slide is kept steady in its movements by the head of thestoppin and the guide 0 In Fig. 5 of the drawings ordinary jaws ofwire-heddle machines are shown on each side of the eye-former, forgrasping the two strands of wire; and these jaws are provided with meansby which they are revolved for the purpose of twisting the said wirestrands around the eye-former. In this figure, F F represent twocylinders, which contain the grasping and twisting jaws z i i t, and GrG the gears which produce the necessary rotation in opposite directions.In this figure of the drawings, the jaws B B are represented as opened,or in the same position as in Fig. 2 of the drawings, for the purpose ofeflecting the shaping of the heddle-eye and tightening the twiststhereof at a: w.

I contemplate, as a modification of the described construction, a planin which, before the jaws holding the wire strands are released, onepart of the eye-former shall first be forced to one end of the heddleeye, and then the other part to the other end of the eye, thus jammingthe eye into shape and tightening the twists; and, under such operation,the jaws would be moved separately, instead of both togethersimultaneously. I also contemplate using an eye-former one jaw of whichis fixed and the other movable. I also contemplate using an eye-formermade of one piece and vibrated from end to end of the heddle-eye for thepurpose of stretching it and tightening the twists.

My device may be applied to various ma chines now in use for the purposeof making wire heddles.

Operation: The wire is drawn into the heddle-machine by the ordinarymechanism for the purpose. Then the points of the eye former and shaperfor the warp-eye are inserted between the strands of wire, and duringthe process of twisting the eye, or after the process is completed, andthe heddle ready to be discharged from the machine, the reciprocatingslide of the eye former and shaper is forced in the direction of thearrow 1 by proper mechanism, and the jaws thereby moved apart, andcaused to produce a stretching effect upon the inside of the weaving orwarp eye of the heddle, and a tightening of the twists at each end ofthe eye. This done, the jaws are closed by the spring and withdrawn fromthe finished eye, ready for another operation.

In practice the jaws may be used slightly apart while the wire is beingtwisted into a heddle-eye upon them.

What I claim as new, and desire to secure by Letters Patent, is-

The heddle-eye forming and finishing con-' trivance, consisting, mainly,of jaws B and an actuating-slide, O, substantially as described, adaptedfor forming the heddle-eye and finishing the same, as specified, andoperated as set forth.

Witness my hand in the matter of my application for a patent for animproved machine for forming the warp-eyes of wire heddles this 13th dayof February, 1877.
